Foundation work in Trenton
Trenton's Building Department issues the city's permits from City Hall at 2800 3rd Street, phone 734-675-6500, Monday to Friday 8:30 a.m. to 5 p.m., with online applications through BS&A; the city page says plumbing work needs a final city inspection. Of 18,242 residents, most live in older houses, since 84.9 percent of homes predate 1980; the median value is $202,400. Wayne County is EPA radon Zone 3, a county prediction below 2 pCi/L, yet EGLE's action level is 4 pCi/L and its guidance is that cracks sealed alone will generally not fix a radon problem.
We found no Trenton page naming foundation repair as a permit item, so ask when a drain or sump is part of the job. Any contractor above $600 needs a state license. Ask the office for the written scope the inspector will sign off, and keep the permit number with the contractor's license number in one folder. MCL 570.1114 says the contract must state the license number where one is required, and a missing number is a reason to pause. For comparison shopping, Woodhaven is 2.2 miles away and Riverview 2.3 miles.
